<em>Aspose</em>.Cells如何将datatable导出Exce...-aspos

HTML 到 Excel ，最好是抄使用 加载 Excel 模板，然后填入数据的导出袭方式。
因为Excel对html标签的样式兼容性存在很大的问题。百

你可以看度看 aspose.Cells 这个插件的说明书。

Aspose.Cells要将数据库绑定到一个工作表，应遵循以下步骤：
访问将被绑定的表
指定一个数据源e799bee5baa6e997aee7ad94e78988e69d83365（可以是一个DataSet，DataTable或DataView等）的工作表
创建列绑定到数据源
创建验证。在我们的实例中，我们将为ProductID列创建一个必要的验证
指定数字格式设置。在我们的实例中，我们将产品价格列的数字格式设置为Currency3
加载和填充数据集
实现绑定
实例代码：
[C#]
//Implementing Page_Load event handler
private void Page_Load(object sender, System.EventArgs e)
{
//Checking if there is not any PostBack
if (!IsPostBack)
{
//Accessing a desired worksheet
WebWorksheet sheet = GridWeb1.WebWorksheets[0];
//Specifying Data Source for the worksheet
sheet.DataSource = dataSet11;
//Specifying Products tables as the DataMember
sheet.DataMember = "Products";
//Creating data bound columns automatically
sheet.CreateAutoGenratedColumns();
//Creating REQUIRED validation for ProductID column
Validation v = new Validation();
v.IsRequired = true;
sheet.BindColumns[0].Validation = v;
//Setting Number Format of ProductPrice column to Currency3
sheet.BindColumns[2].NumberType = NumberType.Currency3;
try
{
//Filling DataSet
oleDbDataAdapter1.Fill(dataSet11);
}
finally
{
//Closing database connection
oleDbConnection1.Close();
}
//Binding worksheet with DataSet
sheet.DataBind();
}
}
